The probability of derailment caused by suspension in the air will be extremely small. From a global perspective, there will be certain risks in railway construction in any country, but some countries have higher risks and some countries have lower risks. China's railway construction technology is at the forefront of the global level, but there are still few news reports of train derailment or high-speed rail derailment. Although the maglev train is suspended in the air, the probability of derailment can be greatly reduced by using the principle that magnets attract in opposite directions and repel in the same direction. According to the data analysis of relevant experts, the derailment probability of maglev train will reach 0. 1 in one million, and the probability of preventing derailment in subsequent maintenance and inspection may reach 100%.
The speed of maglev train will be greatly improved. As the saying goes, to develop the economy, we must develop good transportation. The traffic in the east of our country is very developed. Whether by plane, train or high-speed train, you can reach anywhere in China in a short time. As a new type of train, magnetic levitation can reach a maximum speed of 1000km/h, which is basically suitable for airplanes, so it is also called magnetic levitation, and it is an airplane on the ground. The top speed of ordinary high-speed rail reaches 350 kilometers per hour, which is about 1/3 slower than maglev train. It takes only 6-7 minutes to get from Shanghai to other areas by maglev train, and it may take 20 minutes or half an hour by train or high-speed rail.
In a word, the reason why maglev train is suspended in the air must have its science and technology and corresponding principles. For example, the maglev train is suspended in the air, which can reduce the friction with the rails and reduce the wear and consumption of the train.
